BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a tablet personal computer cover structure, and more particularly, to a cover structure having male and female rotatable buckles so that the tablet personal computer cover received in the cover structure can be rotated. The present invention can carry the tablet personal computer with ease and use the tablet personal computer conveniently.

2. Description of the Prior Art

A conventional rotatable cover structure comprises a foldable member to connect a leather cover and a cover interlayer. The leather cover has a plastic frame at in inner side to receive a tablet personal computer which is inserted from one side of the leather cover. A support frame is provided on an outer side of the leather cover for standing on a table. When the tablet personal computer is used, the support frame is folded reversely with its bottom edge against the leather cover to form a simple support with the leather cover. The user can direct touch, listen or view the screen of the tablet personal computer. The tablet personal computer can be taken along and protected by the leather cover. However, the user is confined to use the tablet personal computer on a table, he/she cannot use the tablet personal computer anywhere by holding the tablet personal computer to use the cam of the tablet personal computer. Besides, the plastic frame is easily damaged and suffers wear and tear after a period of time, which may be unable to protect the tablet personal computer.

Another conventional leather cover has a cam hole corresponding in position to the cam of the tablet personal computer and the foldable board also has a cam hole, so that the user can take a picture with the tablet personal computer. However, the diameter and depth of the cam hole of the foldable board may influence the light when taking a picture, which results in that the cam can't be used on the table.

Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve the problem.
